I undervent a midface augumentation 4 months ago. I am regretting the procedure as the midface tissue seems lowered in my face and my prominent good looking jaws seems smaller. I have talked to other plastic surgeon that said that I looked perfectly fine before the procedure so they would not have put this in my face. The material is PEEK and its fastened with titanium screws. 3 - 4 mm projection covers a large area of my midface. I know consider removal of this but are afraid of sagging
